  The first I heard of it in the 1980s. TI used a laser to project point on a rotating surface. Then someone used a flexible mirror in front of a speaker. The mirror would flex convex/concave changing the apparent distance to a vector display screen. Just saying a modern 1000fps display could do this much better.

    That flexing mirror idea is really smart.
